si-ECIFIGATION forming part of Letters Patent N 0. 743,114, dated November 3, 1903. Application filed September 22, 1902. Serial No. 124,331. (No model.)

To all whom it may concern.-

Be it kn own that I, EMORY A. TRUSSELL, a citizen of the United States, residing in the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Temporary Binders, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to that class of temporary binders used for holding loose sheets of paper and embodies means whereby the sheet-receiving prongs are actuated to move them together or separate them, so as to confine the sheets or permit their removal. The construction provides for the actuation of a series of two or more pairs of sheet-holding prongs simultaneously by the operation of a single part.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a perspective View of a temporary binder constructed in accordance with my invention. Fig. II is an enlarged inside view, the central portion of the binder being partly broken out. Fig. III is a section taken on line III III, Fig. II, with the sheetholding prongs in closed condition. Fig. IV is a section taken on line IV IV, Fig. II, with the sheet-holding prongs shown in open condition. Fig. V is a perspective view of the heel end of one of the prongs. Fig. VI is a perspective View of the heel end of the prong that mates with that shown in Fig. V. Fig. VII is a perspective view of one end of the prong-operating slide.

1 designates the covers of the binder, which are connected to the back2. These parts may be of any desirable construction such as usual in temporary binders.

3 designates a back plate attached to the inside face of the binder-back 2.

carries a longitudinal rib 4, extending from end to end of the plate and preferably formed by a fold at the center of the plate that contains a pivot-rod 5, seated in a pocket in the rib.

6 designates the arch sheet receiving prongs, which are arranged in pairs and exert pressure against the prongs.

This platemounted on the pivot-rod 5, as seen most clearly in Figs. III and 1V. Each prong is provided with a heel 7 ,that projects to the far side of the pivot-rod from that occupied. by

the body of the prong and furnishes a leverarm, against which pressure may be brought to bear for the purpose of moving the prong in the manner hereinafter stated. The free end of one of each pair of prongs is provided with a point 8, and the opposing prong contains a socket 9, adapted to receive said point when the prongs are brought together into closed condition.

1O designates a slide seated longitudinally on the rib 4 of the back plate 3 and adapted to ride therein. The slide 10 is provided with side flanges 11, and projecting from said flanges, adjacent to the prongs 6, are cams or lips 12, that are adapted to be moved withthe slide longitudinally of the rib lto The slide 10 is cut away at the locations of the prongs 6 to permit its longitudinal movement to a limited extent, and projecting upwardlyfrom the inside edges of the flanges 11, within said cut-away portions, are cams or lips 13, which are looted in opposition to the cams 12. The cams 13 are adapted to ride beneath the heels 7 of the sheet-receiving prongs, as seen in Fig. IV.

14 is a knob applied to the slide 10.

In the practical use of the binder the prongs are manipulated to separate or open them and bring them together or close them, as follows: When theprongs are in closed condition, as seen in Figs. I, II, and III, and it is desired to open them, the knob is grasped and the slide drawn outwardly. In this movement of the slide the cams 13 are caused to ride beneath the heels of the sheet-receiving prongs 6 and by pressing against said heels swing them upwardly and cause the prongs to be thrown outwardly in opposite directions into the position illustrated in Figs. II and IV. A reverse movement of the slide carries the earns 13 away from their previous position beneath the heels of the prongs, and continued movement conveys the earns 12 beneath the bodies of the prongs at their rear faces, and said last-named cams are thereby caused them into closed condition.

It will be, seen that by the construction embodied in my invention I am able with the greatest ease to manipulate the sheetreceiving prongs into either open or closed condition and simultaneously throughout the binder where either two or a greater num ber of pairs of mating prongs are made use of. It will also be seen that the prongs are held firmly in either open or closed condition at all times by reason of either the closing or opening cams being in engagement therewith, according to the position into which the slide that carries the cams has been moved.

I claim as my invention 1. In a temporary binder, the combination of a fixed pivot member, two sets of pairs of sheet-holding prongs swingingly mounted on said fixed member, and means for engaging all of said prongs in multiple to move their free ends toward and away from each other simultaneously, substantially as set forth;

2. In a temporary binder, the combination of a fixed pivot member, two sets of pairs of mating sheet holding prongs swingingly mounted on said fixed pivot member, and means for actuating all of said prongs in unison to move their free ends toward and away from each other simultaneously,substantially as set forth.

3. In a temporary binder, the combination of a fixed pivot member, two sets of pairs of mating sheet receiving prongs swingingly mounted on said fixed pivot member, and a slide for engaging all of said prongs in unison to move their free ends toward and away from each other, simultaneously, substantially as set forth.

l. In a temporary binder, the combination of a fixed pivot member, two sets of pairs of mating sheet receiving prongs swingingly mounted on said fixed pivot member, a slide and cams carried by said slide to bear against all of said prongs in unison to move their and cams carried by said slide to bear against the rear faces of' all of said prongs in unison to move their free ends toward and away from each other simultaneously substantially as set forth.

6. In a temporary binder, the combination of a fixed pivot member, mating sheet-receiving prongs mounted on said pivot member,

heels carried by said prongs and projecting beyond said pivot member, means for engaging said heels to move the sheet-receiving ends of said pron gs away from each other, and means for moving the sheet-receiving ends of said prongs toward each other, substantially as set forth.

7. In a temporary binder, the combination of mating sheet receiving prongs, heels carried by said prongs, a slide and cams carried by said slide adapted to bear against said heels, substantially as set forth.

8. In a temporary binder, the combination of mating pivotally-mounted sheet-receiving prongs, heels carried by said prongs, a slide, cams carried by said slide and adapted to bear against said heels, and cams carried by said slide adapted to bear against the rear faces of said prongs, substantially as set forth.

9. In a temporary binder, the combination of a plate, a rib 011 said plate, a pivot-rod located in said rib, prongs mounted on said pivot-rod, a slide arranged to ride on said rib, and cams carried by said slide adapted to engage said prongs, substantially as and for the purpose set forth.
